braked trailer axles-manufacture,factory,supplier from China

The trailer axle is a typical driven axle, its main function is load bearing and auxiliary braking. Compared with the drive steering shaft, the structure of the trailer axle is relatively simple, mainly composed of axle body assembly, brake assembly, wheel end assembly, camshaft assembly and other components.From a structural point of view, common trailer axles are mainly divided into the following types:1. Drum trailer axleThe drum trailer axle is the most widely used trailer axle in the domestic market.

The axle is one of the key parts of the semi-trailer, which is responsible for the load bearing, braking and maintenance of the vehicle. Many owners in the purchase of axles will face a problem: why look similar trailer axles, the price is so much different? Today, let's have a good talk about this topic.First, the choice of raw materials.In fact, no matter what brand of axle, its raw material is basically steel.

What is the fatigue test for? Why do trailer axles need fatigue tests? Today, let's walk into the production workshop of DARO Group to take a close look at the work of the fatigue test bench.When choosing an axle, many owners want to understand the basic situation of the product from all aspects, such as strength, toughness, load-bearing force, service life and so on. However, these data are often just a number or adjectival appearance, many owners feel more boring, after reading, listening to no impression.

In recent years, China's logistics and transportation industry has gradually developed in the direction of intensification and efficiency, and logistics enterprises have more urgent needs for efficient vehicles.

Lightweight is the mainstream trend in the current automotive industry, and freight vehicles are no exception. Driven by this trend, the application frequency of airbag axles is becoming higher and higher, from tractor to semi-trailer, it can be seen.Compared with the steel bridge, the airbag trailer axle is light in both material and weight, leading many owners to question whether it can afford the weight of the goods.In fact, such doubts are unnecessary.

The axle is one of the key load-bearing components of the vehicle. The upper part is connected to the vehicle body through the suspension, and the two ends are used to install the wheels, which can not only support the weight of the vehicle body, but also maintain the normal driving of the vehicle on the road.The axle can be integral, which looks like a big barbell, or it can be disconnected, like two umbrellas inserted on both sides of the vehicle body.

For a long time, brake safety has been a very concerned issue for car owners. For freight vehicles, the load is usually relatively large, the inertial effect of braking is also relatively strong, especially in the need for continuous braking on the road, the brake often appears hot because of frequent braking. The water-cooled trailer axle is a product for the overheating of the brake.Water-cooled trailer axles first appeared in the public eye about 17 years ago, which was a relatively new invention at that time.

Axle is one of the important parts on the semi-trailer, to fully protect the attendance, safety and economic efficiency of the semi-trailer in the long-distance journey, it is vital to choose a high-quality axle.Nowadays, lightweight has gradually become a trend in the semi-trailer industry, and more and more owners prefer to choose those products with stable performance and lighter weight when they purchase semi-trailers or accessories.

Common trailer axles can be divided into four types: drive axle, steering axle, steering drive axle and support axle.1.

Under normal circumstances, the trailer wants to achieve lightweight, there are the following common ways:1, the use of lighter weight materials, such as aluminum alloy instead of steel, common like aluminum alloy body, aluminum alloy transmission, aluminum alloy drive shaft, aluminum alloy fuel tank, aluminum alloy rim, etc.;2, the vehicle appearance and interior parts use new materials, such as long fiber reinforced materials, low density PP materials, low VOC green materials, spray free materials, halogen-free flame retardant materials, etc.;3, reduce the thickness of the plate, the use of
